Hydroxylapatite is widely used in biomedical applications due to its compatibility with human bone tissue. It is commonly employed as a coating for dental implants and orthopedic prosthetics to enhance their integration with bone. In dentistry, it is used in toothpaste and dental care products to remineralize tooth enamel and reduce sensitivity. Additionally, hydroxylapatite is utilized in bone graft materials and scaffolds for tissue engineering to promote bone regeneration and repair. Its bioactive properties make it a valuable material in regenerative medicine and reconstructive surgeries.
